Conventional security band logical is crossed bandage-winder and reclaimed, but bandage-winder recovery effect is only limitted to the upper bands body of effect on human body chest；It is existing
Some dististyle pretension assemblies may act on lower bands body, shows consideration for lower bands and closes human abdomen, bandage-winder and dististyle pretension assembly
With the use of safety belt can be allowed to be bonded driver and conductor completely, security performance is lifted.But the emergency capability of existing dististyle pretension assembly
Deficiency, it is embodied in when accident and driver and conductor's forward lean occur for vehicle, dististyle pretension assembly can not firmly pinion department and multiply people
Member, so as to there is application risk.
The content of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of dististyle pretension assembly, the dististyle pretension
Assembly can securely fix driver and conductor in accident, prevent from departing from, and lift security.
In order to realize above-mentioned purpose, the utility model employs following technical scheme：
Dististyle pretension assembly, it is characterised in that：Gas generating assembly, and be connected on gas generating assembly working end
Pretension pipe, and the pulling assembly being arranged in pretension pipe, and the drawstring that one end is connected with the pulling assembly, Yi Jilian
The latch hook being connected on drawstring the other end；The gas generating assembly includes pedestal, and the gas generation on pedestal
Device；The pedestal is provided with internal first mouth of pipe and second mouth of pipe communicated, and the gas generator is arranged on first mouth of pipe,
Pretension pipe is connected on second mouth of pipe；The pulling assembly includes piston bush；The surface of piston bush is provided with locating slot, and locating slot leans on
Nearly pedestal side is vertical sidewall, and locating slot is sloped sidewall away from pedestal side；Steel ball circle is provided with the locating slot.
Preferably, the inner face of second mouth of pipe is provided with sealing shroud and O-ring seals, drawstring sequentially passes through sealing
Set and O-ring seals.
The utility model uses above-mentioned technical proposal, and the technical scheme is related to a kind of dististyle pretension assembly, the dististyle pretension
Latch hook in assembly latches available for safety harness, when safety belt lock ring is caught in lock, the gas of dististyle pretension assembly
Generating assembly works, and promotes pulling assembly to move through drawstring and tenses latch hook, so that lower bands, which are shown consideration for, closes human abdomen,
And traditional bandage-winder can allow upper bands to show consideration for conjunction human chest, both allow safety belt to be bonded driver and conductor completely at cooperation, lifting
Security performance.
Further in the technical scheme, when accident and driver and conductor's forward lean occur for vehicle, in the work of drawstring
Under, piston bush is pulled to pedestal direction；Steel ball circle is moved rearwards relative to piston bush, i.e., is moved to inclined side wall；Herein
In the case of steel ball circle expanded along inclined side wall, and offseted with the pretension pipe, so as to pin piston bush, prevent piston from packing into
The forward movement of one step；So as to securely fix driver and conductor in accident, prevent from departing from.
Brief description of the drawings
Fig. 1 is the structure assembling figure of dististyle pretension assembly.
Fig. 2 is the structure expanded view of dististyle pretension assembly.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is described in further detail.
A kind of dististyle pretension assembly as shown in Figure 1 and 2, gas generating assembly, and it is connected to the work of gas generating assembly
